LG 60PV450 plasma burning/melting plastic on z-sustain, salvagable?

[progrmmer]

Hi, I have an LG 60PV450 plasma that had a perfect picture but started to smell like it was burning. Took back panel off and saw plastic was all melted on the Z-sustain part that connects to the ribbons cables. Well, now I have the ribbons cables disconnected from the board but as you can see in the pics, one is looking a little rough.

So I have two questions, first, can I even source one of these z-sustain boards anymore? If so, where? Everywhere I've looked just says discontinued. And secondly, is the ribbon cable still usable? I mean, before removing it from the board the TV worked fine - well, aside from burning up...Can the ribbon cable be cleaned up some?

2 images of the "bad" ribbon cable:

Thanks for any help anyone can provide!

to be honest, that looks dangerous. Looks like a fire waiting to happen and I'd think whatever protective finish was on that panel ribbons is long gone and will continue to corrode and arc.

I'd salvage any useable parts and bin it but even the Zsus like discolored by a lot of heat.

+1 these Lg 60" Plasmas are shit anyway riddled with faults.

Thanks everyone, I guess it's time to move onto LEDs

All those contacts are shorted together and though it's probably not advisable the set would probably run with only one connector plugged to the panel.

Though I wonder what caused the fault in the first place.

Last year I had pulled the z sus board to re-solder a couple pins that are notorious for going bad. When I re-installed it I left off one of the gold screws that hold the board in place. After turning it on I noticed a burning plastic smell. I took the back off and noticed the missing screw, as well as some melting on the upper contact of the z sus. I put the missing screw in and re started the TV and everything worked fine, no burning smell or anything. Fast forward a year and the burning smell came back, even though TV was working fine. Probably has to do with the initial melting of the contact, just took a while to really go bad I guess.
